[AT] Engine Cleaner

[vschwartz1 at comcast.net]

At the risk of starting something here that I would rather not I will put this question to you folks. My pickup is 12 years old, and I would like to use some kind of a spray on engine cleaner. The engine is not real dirty, but I would like to clean up the engine compartment and the engine. The engine is gasoline, and I cleaned it one time, a long time ago. I have been to Wal-Mart, O'Riley, and a couple of other auto parts stores. The best offer I have had so far is Gunk cleaner, which I am not too proud of. I would like something better. I saw a pickup a few days ago, that was almost as old as mine. That pickup engine was super clean and shined better than new. I do not expect mine to ever look like that. 
Anyone have any ideas, I would surely appreciate it.
